  • DLSS 4.5 Outperforms AMD FSR in Test with 6,700 Gamers

    DLSS 4.5 Outperforms AMD FSR in Test with 6,700 Gamers

    Key Takeaways

    1. Test Overview: A blind test by ComputerBase compared DLSS 4.5, AMD’s FSR 4, and native rendering with over 6,500 gamers participating.

    2. Results: DLSS 4.5 was the most preferred option, chosen by 48.2% of participants, while 24% chose native quality and 15% preferred FSR 4.

    3. Game Variety: The evaluation included popular titles like Anno 117, ARC Raider, Cyberpunk 2077, and Last of Us Part II, conducted at 4K resolution using the “Quality” preset.

    4. Improvements in DLSS 4.5: Although DLSS 4.5 shows noticeable improvements, it does not represent a drastic change from DLSS 4.0.

    5. Conclusion on FSR: The results do not definitively prove FSR is inferior to native rendering, but DLSS 4.5 is favored among gamers.

    In a recent blind test organized by the notable German magazine ComputerBase, DLSS 4.5 was compared to AMD’s FSR 4 and native rendering. This test saw participation from over 6,500 gamers, and the outcome was quite definitive – DLSS 4.5 triumphed in the upscaling preferences by a significant margin.

    Test Details and Preferences

    The evaluation included a variety of games, such as Anno 117, ARC Raider, Cyberpunk 2077, and Last of Us Part II. In the end, out of all participants, 1,619 (which is 24%) chose native quality, about 1,013 (around 15%) favored AMD’s FSR 4, while a substantial majority, approximately 3,249 (48.2%), opted for Nvidia’s DLSS 4.5.

    Additionally, about 866 (12.8%) of the gamers felt that the three options were almost on par. The test was performed using the “Quality” preset and at a resolution of 4K.

    Improvements in DLSS 4.5

    While DLSS 4.5 may not represent as significant a leap from DLSS 4.0 as DLSS 4.0 did from DLSS 3.0, the enhancements are as apparent as a bright sunny day. Nvidia’s second-gen transformer model demonstrates its effectiveness in practical tests, including the thorough one we conducted.

    It’s important to note that ComputerBase’s findings don’t necessarily undermine AMD’s FSR; they simply reflect the gamers’ first choice, not the subsequent preferences.

    Conclusion on FSR and DLSS

    As stated by ComputerBase, to claim that “FSR is worse than native” based on these survey results would be misleading. Nonetheless, it is clear that DLSS 4.5 seems to have the advantage overall.

    If you’re looking to buy a graphics card, the Gigabyte RTX 5070 Windforce is currently priced at $650 on Amazon.

  • VKD3D-Proton 3.0 Launch Enables AMD FSR 4 on Steam Machines

    VKD3D-Proton 3.0 Launch Enables AMD FSR 4 on Steam Machines

    Key Takeaways

    1. VKD3D-Proton 3.0 introduces support for AMD FSR 4 upscaling, enhancing compatibility for Proton on Linux gaming platforms.
    2. FSR 4 can be simulated on older AMD RDNA 2 and RDNA 3 GPUs using INT8 and Float16 options, allowing more users to access this feature.
    3. Valve seeks official driver-level support from AMD for FSR 4 on Steam Machines to improve performance and visuals.
    4. The robust Zen 4 CPU in Steam Machines may help achieve higher framerates, but potential performance drops are a concern for 4K visuals at 60 FPS.
    5. Native driver support for FSR 4 could give Valve a competitive edge against consoles like the PlayStation 5, especially in ray tracing-enabled games.

    VKD3D-Proton, a key component for compatibility in Valve’s SteamOS and other Linux gaming projects, has been updated to version 3.0. This new version introduces support for AMD FSR 4 upscaling, aiming to implement FSR 4 more effectively in Proton.

    Interesting New Features

    What stands out about this update is that while the standard version only activates the feature on AMD RDNA 4 GPUs or newer, there are options to simulate AMD FSR 4 on graphics cards that support INT8 and Float16. This is similar to the FSR 4 mods previously available, which allowed AMD FSR 4 to work on RDNA 2 and RDNA 3 GPUs, relying on a leaked FSR 4 Int8 DLL. The patch notes mention that the choice not to make this emulation option standard is “over my pay grade.” However, it provides AMD RDNA 2 and RDNA 3 GPU users on SteamOS a way to enable FSR 4, which could have positive implications for both Steam Machines and Steam Decks.

    Valve’s Ambitions

    One comment that supports the notion that this could lead to AMD FSR 4 being supported on Steam Machines is Valve’s expression to Digital Foundry about wanting official driver-level support from AMD. The workaround for FSR 4 using INT8 on Windows and now Linux comes with a performance cost compared to FSR 3, which is necessary to produce better visuals on older RDNA GPUs.

    Performance Considerations

    The robust Zen 4 CPU in the Steam Machine should aid in achieving higher framerates with FSR upscaling. However, the potential performance drop may pose a challenge for Valve’s ambition of delivering 4K visuals at 60 FPS for all Steam games. To keep FSR 4 from taxing graphics performance excessively, some level of official support will likely be essential. This concern is magnified when considering the challenges posed by ray tracing in games like Indiana Jones and the Great Circle.

    As testing on a comparable Steam Machine PC build has shown, GPU performance is a significant worry ahead of the Steam Machine’s release. The advantages of SteamOS for gaming, along with the capabilities of Zen 4, could still position Valve to produce a genuine competitor to the PlayStation 5. Since PSSR is only functional on the PlayStation 5 Pro, having native driver support for FSR 4 on Steam Machines could provide Valve with a crucial advantage.
